• Ar-40-Ar-39 dating
• Geochemistry
• Middle-Late Permian
• Tabei uplift
• Tarim Basin

Five magmatic samples were collected from the wells in the west of Tabei uplift, with the Ar-40-Ar-39 dating results between 267.44 +/- 3.01 Ma and 248.75 +/- 6.5 Ma. According to the geochemistry analysis, we get that the magmatic samples are intraplate rocks characterized with the rifting. Combined previous research, this paper point out that the volcanic activities in Tarim Basin were not only developed in Early Permian but also in Middle-Late Permian. The volcanic activities happened in Middle-Late Permian was the later hot event caused by the Tarim Early Permian Large Igneous Province.
